Looking for a bog standard fuel pump for my ST170, but seems its trickier that it seems, really not keen on second hand ones as could end up back in the same position,

I had one of the Graham Goode ones fitted before xmas but it kept throwin a fault up and the car wouldnt run at all,

So has anyone got any reccomendations for fuel pump thats a simple swap that will/should work out the box ?
